The universally Republican-sponsored bill was held up as responsible insurance that America will continue to lead the world in space exploration.

But the boosts to the exploration budget would come at the expense of NASA’s wide-ranging earth sciences program.

NASA’s 2016 budget would dedicate $1.947 billion of its total funds to the official study of earth. The version in Congress would chop that allotment down to $1.45 billion.

NASA would probably feel a 25 percent cut. Yes, it’s a space agency, but it also works to understand our home planet. NASA currently operates a fleet of 20 Earth-facing satellites, which measure and study everything from ocean currents to rainfall to atmospheric carbon dioxide levels.

Within the atmosphere, airborne science missions survey local climate features, such as earth’s changing polar ice, and help develop technologies to implement in future space missions. (Video via NASA)

In a statement this week, NASA Administrator Charles Bolden decried the proposed “gutting” of these programs and warned the budget "threatens to set back generations worth of progress in better understanding our changing climate."

Ah, the magic words. Critics of the bill see this as a partisan political issue, some vehemently so. (Video via NASA)

At Slate’s Bad Astronomy blog, Phil Plait writes: "Republicans in the House and Senate don't want NASA studying Earth, because they think (or say) that global warming isn't real, or isn't a problem, or whatever talking point they’ve been told to use this week."

"The best scientists in the world are all telling us that our activities are changing the climate," President Obama said in his 2015 State of the Union address. "And if we don’t act forcefully we'll continue to see rising oceans; longer, hotter heat waves; dangerous droughts and floods."

And in an op-ed at The Hill, Texas Democrat Eddie Bernice Johnson wrote, "It’s hard to believe that in order to serve an ideological agenda, the majority is willing to slash the science that helps us have a better understanding of our home planet."

And any politically-driven changes, if that’s what these are, can have significant effects on NASA’s operations. The agency doesn’t really have money just sitting around.

While NASA’s actually set to receive more funding than it did this year, and more than it did in 2014, compared to the overall U.S. budget NASA's share is kind of pocket change.
